A bag contains 3 marbles: a red one, a blue one, and a yellow one. Suppose that two marbles are selected without replacement.
(a) How many outcomes are in the sample space?:::3*2 = 6
List them:: rb,ry,br,by,yr,yb
--------------------------------
(b) What is the probability that a red marble, and then a yellow marble (in that order) are selected?
Ans: 1/6
-----------------------
(c) What is the probability that a red marble and a yellow marble (not necessarily in that order) are selected?
Ans: 2/6 = 1/3
-----------------------
3. A bag contains 3 marbles: a red one, a blue one, and a yellow one. Suppose that two marbles are selected with replacement.
Sample space 3*3 = 9
rr,rb,ry,bb,br,by,yy,yr,yb
